First off, I want to say this is a great product. I write this review specifically for those looking to replace or match a similar Costco product.We have 3 other similar shelves from Costco. We were specifically looking to add a fourth, to match our others. We wanted to get the exact same product as we hoped to stack two side by side along the length of a long, low ceiling room. When I learned earlier this year that Costco was no longer going to supply these, I started looking at other ways to obtain one exactly like what we already have (used markets, wholesalers, etc). I came across this one, which looked exactly the same, and several reviews alluded to it being the same as the Costco product, so I hoped that somehow this was the same as Costco often rebrands items specifically for their stores. We received it today, and although I am very happy with the quality, appearance, and how easy it was to put together, I did want to confirm it is not the same. Luckily, we had a backup plan and will put this one in a place where it doesn't have to match the others, but we really were hoping to find the same product so they could match side by side. On its own, I definitely give this 5+ stars and would order again. It was well packaged, delivery was very efficient, and it seems like good quality. If you want a product on its own, or similar to the quality of what Costco used to carry (I find both versions much higher quality than other ones I have seen from Target, Closetmaid), then I highly recommend this one, but if you are looking for exactly the same one, these are not the same.There are a few differences, which may be either a pro or con, depending on what you are after: This one is slightly narrower by about an inch (when displayed horizontally), this one is slightly more of a grey/ash color (we like the color, but it is lighter if you are looking for a match), and the the long edges (top and bottom if horizontal) are rougher. It appears this product preferences a vertical use, as the vertical/shorter top and bottom surfaces have smoother finish than the top and bottom (long pieces) when horizontal. Again, not a pro or con, just mentioning for reference. The quality of the two seem quite similar, although I would say this one is a bit lighter, but still well built.
